AUXILIARY DEVICE FOR GAS-ENGINES.

Specification of Letters Patent.

Patented May 4, 1920.

Application filed June 27, 1916. Serial No. 106,177.

To all whom it may concern Be it known that I, Jnssn D. LANGDON, acitizen of the United States, residing at Vaterville, in the county ofDouglas and State of Washington, have invented certain new and usefullmpromments in Auxiliary Devices for Gas-Engines; and Ido hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to an auxiliary device for gas engines, and is-more particularly designed for use in connection with automobileengines, and embodies improvements in the construction disclosed in myformer Patent No. 1,186,319, dated June 6, 1916.

One of the objects of this invention is the provision of a deviceconnected with the main water cooling system of the engine in a mannerto provide an efiicient auxiliary cooling and condensing device andwhich is so arranged with respect to the main cooling system of theengine as to provide an efficient device for supplying additional waterto the engine when required.

Another object of this invention is to provide the auxiliarycoolingldevice with a reservoir or container which is normally air tightand its connections water sealed when the water level in the maincooling system of the engine is normal, but which will automaticallyrelease the required amount of water from the reservoir when thewaterlevel in the main cooling system of the engine falls below normalto supply the deficiency.

Another object of this invention is to pro vide a device for the coolingsystem of an internal combustion engine for relieving the excesspressure and the consequent excess temperature within the water jacketand manifold of the engine.

Another object of this invention 'isthe provision of means forrefrigerating the hot water by the explosive mixture of the engine andat the same time to utilize the heat units of the hot water for heatingthe explosive mixture.

A further object of this invention is the provision of means forsupporting the auxiliary cooling device and connecting the same with themain cooling system of the engine at points whereby to efficientlyattain the desired results. 7

A further object of this invention is to provide an auxiliary devicewhich can be readily attached to any of the automobiles and theirengines or to stationary gas engines now in use or which can be built inthe above structure's during their course of construction.

These and other objects and advantages will more fully appear as thenature of the invention is more clearly understood from the followingspecification, the subject matter of the claims, and the viewsillustrated in the accompanying drawings, in which,

Figure 1 is a side view of the front portionoii an automobile, shownpartly in section, showing one form of applying the invention inoperative position upon an automobile.

Fig. 2 is a vertical transverse sectional view on line 22 of Fig. 1looking in the direction of the arrow, showing the means which may beemployed for adj ustably supporting the device if desired.

Referring to the drawings, 1 denotes the portion of the chassis or frameof the automobile, 2 the dash board, 3 the engine hood, 4L the radiator,and 5 the engine having its hot water hood or manifold 6 operativelyconnected with the upper portion of the radiator 4L by the hot waterpipe 7 and also having the lower portion of its water jacket operativelyconnected with the lower portion of the radiator 4 by the cold waterre.- turn pipe 8.

In the drawings I show means for adjustably supporting the device whichconsists in providing the oppositely disposed spaced pairs of supportingstandards 9 secured upon the frame 1, each of the standards 9 beingprovided with the elongated slot 10 for adjustably receiving thethreaded bolts 11 upon the shoulder 12 of the brackets 13 which aresuitably secured upon the reservoir and condenser 14; at substantiallydiametrically opposite points, the threaded bolts 11 being retained intheir adjusted positions by the nuts 15 screwthreaded upon the bolts 11binding the standards 9 between the shoulders 12 of the brackets 13 andthe nuts 15, so that the reservoir 14 may be elevated or lowered tosubstantially the positions shown in full lines and dotted lines in Fig.1 in order to my invention.

hood or manifold 6 will now all suitably position the reservoir 14 withrespect to the engine or to provide for the installing and thepositioning of reservoirs of varying shapes and sizes.

The reservoir 14 shown in Fig. 1 is preferably positioned at a suitablepoint between the engine 5 and the dash board 2 and has its upperportion connected to the hot water hood or manifold 6 of the engine bythe pipe 16-, preferably a flexible pipe, and

the bottom portion of the reservoir 14 is connected to the cold waterunion 17 leading into the water jacket of the engine by the pipe 18,also preferably a flexible pipe, or the connecting pipes 16 and 18 maybe metal pipes having any suitable form of rotatable unions therein ormay be continuous and unjointed pipes if desired. 7

I attain many advantageous results by he feature of the invention beingthat the reservoirs are connected by the pipe 16 to the hot water hoodor manifold 6 at a point where the water is the hottest and where theupward flow of the hot water and steam is obstructed by the backpressure within the pipe 7 leading to the radiator 4 which back pressureis caused by the sudden cooling of the water within the pipe 7 so thatthere is created through the auxiliary cooling device a more completethermosiphonage through the auxiliary cooling device to thereby relievethe excess pressure and the consequent excess temperature within thewater jacket ofthe engine.

Another feature is that the reservoirs remain normally air tight andfull of water and the pipe 16 water sealed so long as the water level inthe main cooling system of the engine is at its normal height but assoon as the water'level in the engine falls sufficiently below itsnormal height to un seal the pipe 16, the air or steam within the freelypass through the pipe 16 and the upper portion of the reservoirs andthereby release a sulfi-- cient quantity of water from the reservoirs tosupply the deficiency of water within the main cooling system of theengine through the pipe 18 to the water jacket of the en gine.

'A further feature resides in the fact of neeapee the reservoirs beingair tight so that when the engine has been stopped for a sufficientlength of time for the engine and the water in the main cooling systemand the water in the auxiliary cooling system to have become cooled, thewater in the reservoirs which I employ will contract and settle. to wardthe bottoms thereof and thereby create a vacuum in the upper portions ofthe reservoirs, whereby upon the starting of the engine and the heatingof the water the vacuum will accelerate the upward flow of the water andimmediately establish circu lation through the auxiliary cooling systemand when the water becomes sufliciently hot the water thereaftercirculates through the auxiliary system by the thermosiphon createdtherein and independently of the regular cooling system of the engine.

Having described my invention, what I claim as new and desire to secureby Letters Patent, is g 1. The combination with the water circulatingmeans of an internal combustion engine including a water jacket and ahot water outlet and cool water inlet for said jacket, of a reservoirhaving flexible connections with said water outlet and inlet for thecirculation of water through said reser voir, and means for mountingsaid reservoir for vertical adjustment with respect to the water jacket.

2. The combination with the water'circulating means of an internalcombustion engine including a water jacket and a hot water outlet andcool water inlet for said jacket, of a reservoir independent of saidwater circulating system disposed at one side of the water jacket,flexible connections between the upper and lower portions of thereservoir and said water outlet and inlet, respectively, and meanssupporting said reservoir for vertical adjustment with, respect to saidjacket.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
